QUESTIONS AND CORRECT ANSWERS WITH RATIONALE
NEW!!!!!!!!!!!!!!!!!!!
This comprehensive WGU C720 Operations and Supply Chain Management
question bank contains 200 unique, non-repetitive multiple-choice questions
aligned with the Objective Assessment competencies. Each question covers
essential topics including process design, capacity planning, facility layout,
inventory management, forecasting, quality management (TQM, Six Sigma,
lean), supply chain strategy, and service operations. Every question includes
four answer options, the correct answer, and a detailed evidence-based
rationale that explains the underlying operations principle. Topics range from
productivity calculations and break-even analysis to quality tools, forecasting
methods, and competitive priorities. This resource provides robust
preparation for students seeking to master operations and supply chain
management concepts.
1. Which of the following best defines operations management?
A) The process of marketing and selling goods and services to consumers
B) The design, planning, and management of processes that transform inputs into
outputs
C) The management of financial resources and investment portfolios
D) The recruitment, training, and development of employees
Answer: B
Rationale: Operations management involves the decision-making processes for the
design, planning, and management of the many factors that affect the
transformation of inputs (people, capital, materials, energy) into outputs (goods
and services). It is distinct from marketing, finance, and human resources functions
.
2. Which of the following is NOT an input in a typical operations system?
A) Raw materials
B) Labor
C) Finished goods
D) Capital
Answer: C
,Rationale: Inputs are the resources used in the production process, such as people,
capital, materials, and energy. Finished goods are outputs, not inputs, because they
are the result of the transformation process .
3. Productivity is best defined as:
A) The total number of units produced in a given time period
B) The ratio of outputs achieved divided by the inputs consumed
C) The total cost of production divided by the number of employees
D) The amount of waste generated during production
Answer: B
Rationale: Productivity is a mathematical calculation that measures the efficiency
of production by comparing outputs achieved to the inputs consumed. The formula
is Output divided by Input. This ratio helps organizations evaluate their efficiency
in using resources .
4. Which of the following is an example of a service operation?
A) Automobile assembly line
B) Hair salon
C) Oil refinery
D) Computer chip fabrication
Answer: B
Rationale: Services are intangible products that cannot be touched or stored. A hair
salon provides a service, while the other options are manufacturing operations that
produce tangible goods .
5. What is the primary focus of supply chain management?
A) Advertising strategies and market positioning
B) The flow of materials, information, and finances across organizations
C) Employee motivation and organizational culture
D) Legal compliance and regulatory affairs
Answer: B
Rationale: Supply chain management focuses on coordinating the flow of
materials, information, and finances from raw material suppliers to the end
customer. It integrates suppliers, manufacturers, distributors, and retailers .
6. Which inventory type consists of parts or materials used to support production
but is not a component of the final product, such as lubricants for machines?
A) Raw materials
B) Work-in-process
C) Finished goods
,D) Supplies
Answer: D
Rationale: Supplies are materials used to support production operations but do not
become part of the final product. Examples include lubricants, cleaning supplies,
and maintenance items. They are distinct from raw materials, which are
incorporated into the final product .
7. A company that produces motors uses a check sheet to collect defect data. Why
would the company use this check sheet?
A) To create a control chart to measure the engine assembly process
B) To create a flow chart of the engine assembly process
C) To develop a suppliers, inputs, process, outputs, customers diagram
D) To develop a Pareto chart identifying the root causes of engine defects
Answer: D
Rationale: Check sheets are used to collect data that can be displayed in a Pareto
chart to highlight the most frequent causes of defects. This tool helps organizations
identify and prioritize quality improvement efforts .
8. A customer went to a service center to have new tires installed. An employee
was polite, professional, and clearly explained the types of tires, the replacement
process, and the warranty. What service quality dimension is demonstrated?
A) Responsiveness
B) Tangibles
C) Assurance
D) Reliability
Answer: C
Rationale: Assurance refers to the knowledge and courtesy of employees and their
ability to convey trust and confidence. The employee's professionalism, clear
explanations, and ability to answer questions demonstrate assurance .
9. A hotel manager periodically inspects each room to assess its condition. Which
cost of quality does this illustrate?
A) Appraisal costs
B) Prevention costs
C) Internal failure costs
D) External failure costs
Answer: A
Rationale: Appraisal costs are investments in measuring quality and assessing
customer satisfaction. Inspecting hotel rooms to evaluate their condition is an
, appraisal activity aimed at identifying quality issues before they reach the customer
.
10. A website makes customers enter their bank payment information twice and
only proceeds if the data matches. Which cost of quality is represented?
A) External failure costs
B) Prevention costs
C) Internal failure costs
D) Appraisal costs
Answer: B
Rationale: Prevention costs are investments designed to prevent defects from
occurring. Requiring double entry of payment information prevents errors by
detecting mismatched data before processing, which is a poka-yoke or mistake-
proofing technique .
11. A small business sends surveys to ask which features people like and which
they would like added. Which total quality management principle is illustrated?
A) Continuous improvement
B) Customer-centered focus
C) Supplier relationships
D) Performance measures
Answer: B
Rationale: A customer-centered focus, a core TQM principle, means understanding
customer needs and expectations. Sending surveys to gather customer feedback on
product features is a direct application of this principle .
12. A company sources many components from another business and has
collaborated to customize the components for optimal quality. What TQM concept
is demonstrated?
A) Supplier relationships
B) Continuous improvement
C) Performance measures
D) Employee involvement
Answer: A
Rationale: TQM emphasizes developing strong supplier relationships to improve
quality. Collaborating with suppliers to customize components demonstrates a
commitment to building partnerships that enhance product quality .
